I'm trying to run a java class on my 400. But I'm getting an UnsupportedClassVersionError. I compiled the class in Netbeans with version 1.4.2. Which is what java -version shows in QSH on the iSeries.

If I try to do a JAVAP -Verbose on the class, it returns major and minor versions of both 0. Is there any way to debug this error further?

Some ideas:

Run javap on your pc against the java class file

Double check that the file was transferred in binary mode if using ftp.

Ensure you don't have a JAVA_HOME variable set.

Force the java version with "java -Djava.version=1.4 MyClass"

Use "java -verbose MyClass" to see when the class breaks.
